methods and instance variables
instance variables and their values
access modifiers of the instance variables
O
methods and their return values
Answer:
The right answer is option 2: instance variables and their values
Explanation:
Let us define what an object is.
An object is a blueprint of a real-world identity. The instances are the reference to the object. Multiple instances of an object type can be made.
The instance variables and their values help us to determine the state of the object.
Hence,
The right answer is option 2: instance variables and their values
Write a class called Person that has two data members - the person's name and age. It should have an init method that takes two values and uses them to initialize the data members.Write a separate function (not part of the Person class) called std_dev that takes as a parameter a list of Person objects (only one parameter: person_list) and returns the standard deviation of all their ages (the population standard deviation that uses a denominator of N, not the sample standard deviation, which uses a different denominator).
Answer:
class Person(object):
def __init__(self, name, age):
self.name = name
self.age = age
def std_dev(person_list):
average = 0
for person in person_list:
average += person.age
average /= len(person_list)
total = 0
for person in person_list:
total += (person.age - average) ** 2
return (total / (len(person_list) )) ** 0.5
Explanation:
The class "Person" is a python program class defined to hold data of a person (name and age). The std_dev function accepts a list of Person class instances as an argument and returns the calculated standard deviation of the population.
Conside following prototype of a function
int minArray(int [], int );
Which of the option is correct way of function CALL assuming following arraydeclaration
int x[5] = {7,4,6,2,3};*
a) minArray(x,5);
b) minArray(x[],10);
c) minArray(x[5],5);
d) minArray(5,x);
Answer:
The answer is "Option a"
Explanation:
Following are the code to this question:
#include <stdio.h>//header file
int minArray(int x[], int n)//defining method minArray that accepts two parameters
{
for(int i=0;i<n;i++)//defining loop for print value
{
printf("%d\n",x[i]);//printf array value
}
}
int main()//defining main method
{
int x[] ={7,4,6,2,3};//defining array that hold values
int n=5;//defining integer variable
minArray(x,5);//calling method minArray
return 0;
}
In this code, a method "minArray" is defined, that accepts two parameters array and an integer variable in its parameter, and in the next step, the for loop is declared, that uses the print method to prints its value.
In the next step, the main method is declared, which declared an array and holds its values and defines an integer variables, and calls the method "minArray".
Which results are expected in a personality test but not a skills assessment?

Hydraulic pressure is the same throughout the inside of a set of brake lines. What determines the amount of resulting mechanical
force is the size of the piston in the wheel cylinder or caliper. For example: 100 psi of fluid pressure acting against a caliper piston
with 4 square inches of surface area will result in 400 lbs of clamping force.
A fluid line with 200 psi in it acting against a piston with 3 square inches of area would result in 600 lbs of force.
A fluid line with 50 psi acting on a larger piston with 12 square inches of surface area would result in 600 lbs of force, and so on...
How much fluid pressure would it take to lift a 6000 lb truck on a lift with a 60 quare inch piston (such as on an automotive lift)?
Give your answer and try to justify your answer using an equation or formula.. Pressure x surface area equals mechanical force,
or... force divided by surface area equals fluid pressure
Answer: 1000 square ponds of force hope you know the answer

Type a statement using srand() to seed random number generation using variable seedVal. Then type two statements using rand() to print two random integers between (and including) 0 and 9. End with a newline. Ex:
5.
7.
Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use two statements for this activity. Also, after calling srand() once, do not call srand() again. (Notes)
1 #include
2 #include //
3 Enables use of rand ()
4 int main(void) ( int seedval;
6.
7. scanf ("%d", &seedval);
8.
9.
10 srand(int seedval);
11 printf("%d\n", srand());
12 printf("%d\n", srand());
13
14 return e;
15 }
Answer:
#include<stdio.h>
#include<stdlib.h>
int main(void){
int seedval;
scanf ("%d", &seedval);
srand(seedval);
printf("%d\n", rand()%10);
printf("%d\n", rand()%10);
return 0;
}
Explanation:
The given code is poorly formatted. So, I picked what is usable from the code to write the following lines of code:
#include<stdio.h>
#include<stdlib.h>
int main(void){
This line declares seedval as integer
int seedval;
This line gets user input for seedval
scanf ("%d", &seedval);
This line calls the srand function to generate random numbers
srand(seedval);
This prints a random number between 0 and 9
printf("%d\n", rand()%10);
This also prints a random number between 0 and 9
printf("%d\n", rand()%10);
return 0;
}
